The tag definitions in Hobo can be pretty intimidating. Here's a
stripped down field-list that should be a lot easier to follow:
<def tag="field-list" attrs="fields">
<labelled-item-list>
<with-fields fields="&fields">
<labelled-item>
<item-label>
<%= this_field_name %>
</item-label>
<item-value>
<view/>
</item-value>
</labelled-item>
</with-fields>
</labelled-item-list>
</def>
Now you can modify that to add what you need:
<labelled-item if="&!this.nil?">
Try that out and see if it works -- I may have been a little bit to
aggressive in stripping. You can refer to the original source if
something appears to be missing.
If it works for you, you can try modifying the original field-list in
rapid_core.dryml to make this an optional feature. Then you can send in
a patch. We love getting patches!
cheers,
Bryan
